A pack rat midden is a debris pile constructed by a woodrat. A midden may preserve the materials incorporated into it for up to 50,000 years. [citation needed] These midden piles may be analyzed to reconstruct their original environment, and comparisons between middens allow a record of vegetative and climate change to be built.
Bushy-tailed woodrat on midden Paleo-ecologists have used a variety of techniques to analyze the plant and animal material in pack rat middens describe paleo-communities and infer paleo-climate. For example, the plant species present in middens, and the carbon isotope ratios on material in middens have been widely studied.[7] " all depends on ...

Initially, when their diachronic nature was less evident, they were viewed as the poor relation to the better studied pack rat middens. [37] [38] While pack rat middens are rich in identifiable macrofossils, which can be directly dated and provide high taxonomic resolution, hyrax middens are poor in macroremains. Those that are found are almost ...
